本文介绍了如何通过Spring Boot集成Zipkin，配置客户端和服务端，以及创建两个示例项目client8081和client8082，展示如何使用Sleuth进行服务间调用追踪。重点在于演示了如何配置base-url和使用streaming模式的Sleuth-Zipkin。

一、总体结构

在这里插入图片描述

代码位置：https://gitee.com/DanShenGuiZu/learnDemo/tree/master/zipkin-learn

核心：只要引入如下配置就可以

 <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.8.RELEASE</version>
        <relativePath/>
</parent>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
    <spring-cloud.version>Camden.SR6</spring-cloud.version>
</properties>

 

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-zipkin</artifactId>
</dependency>

 

<!--依赖管理，用于管理spring-cloud的依赖 -->
<dependencyManagement>
	<dependencies>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-dependencies</artifactId>
			<version>${spring-cloud.version}</version>
			<type>pom</type>
			<scope>import</scope>
		</dependency>
	</dependencies>
</dependencyManagement>

二、zipkin-demo02-client8081 代码

2.1、pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>fei.zhou</groupId>
    <artifactId>zipkin-demo02-client8081</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>zipkin-demo02-client8081</name>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.8.RELEASE</version>
        <relativePath/>
    </parent>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <spring-cloud.version>Camden.SR6</spring-cloud.version>
    </properties>
    <dependencies>

<!--            <artifactId>spring-cloud-starter-zipkin</artifactId>-->
<!--        </dependency>-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-sleuth-zipkin-stream</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-stream-rabbit</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-sleuth</artifactId>
        </dependency>


    </dependencies>

    <!--依赖管理，用于管理spring-cloud的依赖 -->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>


</project>

2.2、application.properties

spring.zipkin.base-url=http://localhost:9411/
server.port=8081
spring.application.name=client8081

2.3、Beanconfig

package fei.zhou.zipkindemo02client8081.business.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;

@Configuration
public class Beanconfig {
    
    @Bean
    public RestTemplate restTemplate() {
        RestTemplate restTemplate = new RestTemplate();
        return restTemplate;
    }
}

2.4、HelloController


package fei.zhou.zipkindemo02client8081.business.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

/**
 * 描述该类
 * 
 * @class: HelloController
 * @date 2021/8/22 15:54
 * @author <a href="mailto:zhoufei@smartdot.com">周飞</a>
 * @Verson 1.0 -2021/8/22 15:54
 * @see
 */
@RestController
@RequestMapping("zipkin")
public class HelloController {
    
    public static final String url = "http://localhost:8082/zipkin/service2";
    
    @RequestMapping("/service1")
    public String service() throws Exception {
        System.out.println("-----调用service1-----");
        
        String data = restTemplate.getForObject(url, String.class);
        
        return "service1," + data;
    }
    
    @Autowired
    RestTemplate restTemplate;
    
}

三、zipkin-demo02-client8082 代码

处理以下几个配置，其他都和zipkin-demo02-client8081一样。

注意：

zipkin-demo02-client8082没有Beanconfig配置

3.1、application.properties

spring.zipkin.base-url=http://localhost:9411/
server.port=8082
spring.application.name=client8082

3.2、HelloController



package fei.zhou.zipkindemo02client8082.controller;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * 描述该类
 * 
 * @class: HelloController
 * @date 2021/8/22 15:54
 * @author <a href="mailto:zhoufei@smartdot.com">周飞</a>
 * @Verson 1.0 -2021/8/22 15:54
 * @see
 */
@RestController
@RequestMapping("zipkin")
public class HelloController {
    

    @RequestMapping("/service2")
    public String service() throws Exception {
        System.out.println("-----service2-----");
        
        return "service2";
    }
}
